SMD steel plate laser cutting machine needs a stage of low gravity center and smooth curve motion. This stage accurately employes two linear motors having same trust to mass ratio so that the bandwidths of two axes are exactly the same to achieve perfect curve motion.

- The linear guides of X and Y axes are arranged on the same plane to enhance fast settling and trajectory tracking.
- The up axis and down axis are stacked with a very low profile design.
The distance between working surface of up axis and linear guide mounting surface of down axis is only 60 mm. - The stage employees a bottom base made of cast iron to absorb vibration.
- Built-in cable chain and fully covered bellow to improve protection grade.
- Ultra-low cogging force linear motors are employed.
